This.- invention:relates-.tol a -Lwalllslab 'andi more j particularly toa wall slabffformedloiwcon'cretiousl-.materiafl .and specially adaptedfor use in the erection of buildings.

An object of the invention is to provide a wall slab, of such shape thata -plurality of the slabs may be readily assembled into a completewallwith waterproof joints between vthe slabs, each slab having avertical marginal rib at,r each margin and a vertical intermediate 'ribbetween the marginal ribs, said ribs extending inwardlyk and formingmeans for the attachment of the inside lathing, or other inside wallsupport therey to, thus providing, in eiect, a hollow wall structure. f

Figure l shows a fragmentary Vertical se'cf tional view of a buildingstructure, showing one of the wall slabs in section, and

Figure 2 shows a cross sectional view taken on the line 2 2 of -Figurel.

Referring now more particularly to the drawing whereinlike numerals ofreference designate the same parts in each of the figures, the numeral ldesignates a Wall slab as a whole which is approximately rectangular inelevational view. Each slab .has a vertical groove 2 in one margin and avertical rib 3 on its other margin, the rib or one slab being positionedto fit into the groove of the adjacent -slab as more clearly shown inFigure 2. The grooves 2 may v be lled with a plastic of corkingmaterial, as 4,

during the progress of the work to form water tight joints between theslabs.

Each slab has the inside vertical marginal ribs or flangesas 5, 5.'I'hese flanges taper slightly inwardly and extend from top to bottom ofthe slab. The marginal anges on each slab t closely against the opposingmarginal anges of adjacent slabs as also shown in Figure 2. One of thecornerv slabs has its vertical marginal rib 5a thickened as shown inFigure 2 so that it will be of approximately the same thickness It isanother Yobject of the'- invention to pro--v -as the width of' theabutting ange 61 of# the-adjacent Vsla-b and the inner face of thisthickened flange is` provided with the groove 4 tov receive `theKadjacent-ribv 3l of the aol-jacent slab.

Each slab has also an intermediate vertical 5 rib, orl flange, larranged approximately midway between the marginal flanges and betweenthe marginal anges 5, 6 and the intermediate flange of each slab are thetransverse webs 8, whose inner margins are arcuate as shown. Theupper 10and lower ends of the slabs are inwardly thickened forming thetransverse upper and lower end ribs 9.'v It is to be noted that the siderib 3, the marginal and intermediate'flanges 5, 5, 1,

the transverse webs 8 and the upper and lower 16 transverse ribs S, I0,are formed integrally with -the corresponding slab, thus forming asingle unit. The flanges 5, 6, 1 of the respective slabs extend inwardlythe same distance, so that the innermargins of the flanges of a'wallwill lie 20 in a common plane and these ilanges form means for theattachment of wall lathing -thereto to receive a plastered inside wallor any other selected type of inside wall may be secured thereto. 25

t The numeral ll` designatesl a foundation into which thelowe-r ends ofthe wall slabs may be counter-sunk as clearly shown in Figure l. As a`preferred form of securing the wall slabs to the foundation, an insideangle angle iron as l2 30 may be provided, extending all the way aroundthe structure and being countersunk into the foundation and into thetransverse ribs I0.

bedded in the foundation I l and extend upwardly 40 through thehorizontal leg I8 of said angleiron Withtheir upper en ds threaded toreceive the securing nuts i9, whereby the lower ends of the slabs willbe secured to the foundation.

Across the upper margins of the wall slab is 45 an angle iron 2U whoseupper horizontal leg 2| overlies the upper ends of the slabs and whoseVertical leg 22 ts against the inner margins of the transverse-ribs 9,said angle iron being countersunk into the material of said rib 9. 50

Anchor bolts 23 may be `embedded in the material of the ribs 9 withtheir outer ends extending through vertical slots 24 of the leg 22 andbeing threaded to receive the nuts 25 thereon.

The framework 26 above may be supported on 55 general contour having aplane outer surface,

inwardly extending marginal side anges and an inwardly extendingintermediate flange par'- allel with said marginal flanges, a rib on theouter face of one of said marginal flanges and a groove on the outerface of the other of said marginal flanges, transverse webs between themarginal flanges and the intermediate flange, one of said marginalflanges being thicker than the other of said marginal flanges; areinforcing angle iron counter sunk into the outer corner of saidthicker flange adapted to receive a framework of a building, an anchorbolt em' bedded in the material of said flange and adapted to hold saidangle iron in position.

2. A wall slab approximately rectangular in general contour having aplane outer surface, inwardly extending marginal side flanges and aninwardly extending intermediate flange parallel with said marginalanges, a rib on the outer face of one of said marginal flanges and agroove on thev outer face of the other of said marginal flanges, upperand lower transverse ribs between the marginal flanges and theintermediate anges, an intermediate transverse web between and parallelto the transverse ribs, the upper and lower of said transverse ribsbeing thicker than the web and the flanges and having removed portionsadapted to receive legs of steel beams, boltsimbedcled in saidtransverse ribs and extending outwardly approximately perpendicular tothe plane of the wall slab whereby said structural beams may beconnected to the wall slab.
